The grass around was very long, and mostly of very coarse descriptions, consisting chiefly of a species of uniola growing in tufts, agrostis with creeping roots and broad blades; the horses seemed to like the uniola best.

Above, see those delicate threads of the purple amoret, with its flood of anthers that are nearly yellow; the snowy pyramids of the meadow-sweet, the green tresses of the wild oats, the slender plumes of the agrostis, which we call wind-ear; roseate hopes, decking love's earliest dream and standing forth against the gray surroundings.

Our domestic animals, that have some liberty, are also possessed of some peculiar traditional knowledge: dogs and cats have been forced into each other's society, though naturally animals of a very different kind, and have hence learned from each other to eat dog's grass (agrostis canina) when they are sick, to promote vomiting.
